I also have a autoimmune muscle disease. I was also hungry all the time, but instead of being sleepy, I was wide awake almost all the time....only slept 2 to 3 hrs a day, but had no energy to do anything...talk about wasted time. I took the max of Pred for 5 years and another 2 to get off of it. If I were told I had to take it again, I'd have to think long and hard about it. Some days I felt like I was in another world. Why people take drugs they don't have to is a mystery to me. Hopefully you can get off that 'good' stuff very soon.
